Automatic frequency throttling and voltage adjustment can be enabled by loading the acpi_cpufreq module (this one is to be preferred over the Intel Speedstep ones; those will be deprecated soon). Install cpufreqd, which will pull in cpufreq-utils along with it. Set up both utilities, and add cpufreqd as a daemon to your DAEMONS=() array (in /etc/rc.conf, that is).

Feature-wise this is an awesome GPU. Opensource drivers that support 3D out of the box. However, it has a problem many of the Intel GPUs have: it will stick to VESA resolutions in the framebuffer.

As you can see this is the only resolution. According to the uvesafb FAQ, if that's all you get, not even uvesafb can fix it up for you. For earlier chipsets (865 and 915 for example) tools like <tt>855resolution</tt> and <tt>915resolution</tt> are available, but the latter does not support the Intel G965M yet. However, there is a patch that fixes that :-). You can find an [http://zero9.org/pkgbuilds/915resolution/PKGBUILD adapted PKGBUILD] and a [http://zero9.org/pkgbuilds/915resolution/965-support.patch patch] here. This allows you to set the 1440x900 resolution, but one needs to dig far deeper into the system to get the system booting in that resolution, it seems.

You have two choices for this card, either go with the present (and soon to be phased out) ieee80211 stack, or with the successor, the mac80211 stack. Both are present in the Arch kernel from 2.6.22 on.

I use pm-utils for this, which is pretty straightforward. X tends to hang once in a while after resuming, you can fix this (although not perfectly) by adding the following VBE Tool 'hack' to in /etc/pm/sleep.d/00hacks:<br>

Alternatively, you could leave pm-utils alone and add a so-called [http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-try.html quirk] to HAL's info file - 20-video-quirk-pm-hp.fdi to be specific, right below the line that says

This is the quirk I cooked up, following the instructions on the HAL page:

In the early days, there were a bunch of different hacks that you had to perform in order to be able to suspend/hibernate your 6510b. Nowadays, all you should need is the following:

From hal-info 20071212 on HAL provides this quirk out of the box - no more fiddling needed :-). The HAL quirk means the vbetool lines are no longer necessary in the 00hacks file. You'll still need to change virtual terminal though to have X resume correctly!<br>

+

sudo pacman -S pm-utils

−

A third alternative would be to add some VbeTool options to your Xorg.conf, that seems to do the trick too. Haven't tried it myself, however.

−

If you are using Xfce, you can suspend to RAM or disk from the Xfce logout dialog. You do need a modified session manager for this though. You can find the [http://zero9.org/pkgbuilds/xfce4-session/logout_dialog-suspend-hibernate.patch patch that adds that functionality] and the corresponding [http://zero9.org/pkgbuilds/xfce4-session/PKGBUILD PKGBUILD] online.

That will install the pm-utils package which contains the programs pm-suspend, pm-hibernate, etc. To suspend to RAM, just do the following:

−

Suspend to disk works fine with the 2.6.22 kernels (at least up to 2.6.22.9). Newer kernels do not seem able to suspend to disk without needing the

Pretty straight-forward! There is also a "hybrid", called pm-suspend-hybrid. What this does is that it does everything it needs to hibernate and then ''suspends'' the computer instead of shutting it down, as it normally would when hibernating! So if you do not run out of power during this suspended state, you can start the computer up again as if it was a normal supension&mdash;if you do run out of power, it would just act like a normal hibernation.

FireWire is supported out of the box, however, for FireWire HD support, you might need to load the sbp2 module (that is, if you are using the common stack, since a new one is in the works and already present in the kernel). You have the common stack if you run stock Arch kernels.

As duly pointed out on the forums, fingerprint readers are more a threat to your privacy than a safeguard. Your fingerprints (unless you are paranoid and type with gloves on) are likely to be all over your keyboard, rendering the 'security' purpose of this device useless. Keep this in mind if you intend to use the reader as a replacement for your password; fingerprints can be duplicated easily with basic stuff (graphite ea.).<br>

There is a utility called [http://reactivated.net/fprint/wiki/Main_Page fprint] available, together with a libfprint library it depends on. Both are packaged for Arch Linux. The fprint program is still called fprint_demo for the moment, but it works :-).

People running kernel 2.6.23 on this laptop experience hard lockups when they close the laptop lid. 2.6.22 does not have this problem. It seems also 6710b owners are affected.

This is due to a fix in the ACPI video driver in 2.6.23; however, this messes things up for some hardware... You can fix it by putting this in rc.local:

−

echo 1 > /proc/acpi/video/*/DOS

More info on this 'fix' can be found on [http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=commitdiff;h=a21101c46ca5b4320e31408853cdcbf7cb1ce4ed here]. It seems this behaviour might be changed again with 2.6.24 (before 2.6.23 the value use to be 1 by default), but until it hits stable there is of course no certainty about that :-).

Revision as of 17:35, 14 January 2014

The HP 6510b is a compact yet powerful laptop with a high-resolution screen (if you pick the WXGA+ version). It has been labeled "Novel SuSE Enterprise certified" by HP, which should mean Linux runs fine on it.

Setup

CPU Frequency Scaling

X3100 onboard GPU

Feature-wise this is an awesome GPU. Opensource drivers that support 3D out of the box. However, it has a problem many of the Intel GPUs have: it will stick to VESA resolutions in the framebuffer. Since the only fitting resolution is 1024x768, that is what you'll when using a framebuffer (on boot, and in a command line environment). You can check what modes the GPU supports like this:

[stijn@lysithea ~]$ cat /sys/class/graphics/fb0/modes
U:1024x768p-75

As you can see this is the only resolution. According to the uvesafb FAQ, if that's all you get, not even uvesafb can fix it up for you. For earlier chipsets (865 and 915 for example) tools like 855resolution and 915resolution are available, but the latter does not support the Intel G965M yet.

There are modified PKGBUILDs and patches to fix that, but the URLs provided on this page before do not exist anymore. They allow you to set the 1440x900 resolution, but one needs to dig far deeper into the system to get the system booting in that resolution, it seems.

IPW3945 ABG wireless LAN

You have two choices for this card, either go with the present (and soon to be phased out) ieee80211 stack, or with the successor, the mac80211 stack. Both are present in the Arch kernel from 2.6.22 on. With the former you'll need Intel's proprietary regulatory daemon and firmware, and - last but not least - the driver; the latter does not require any regulatory daemon, but still requires the driver and firmware to be installed.

Note: each driver needs different firmware!

The radio switch is hardware (it sits on the tactile strip), which is pretty convenient. Just touch it and the radio gets enabled. The switch could also be pretty shitty at times, as it will disable radio if you scrape away some dust from the tactile strip.

Suspension and hibernation

In the early days, there were a bunch of different hacks that you had to perform in order to be able to suspend/hibernate your 6510b. Nowadays, all you should need is the following:

sudo pacman -S pm-utils

That will install the pm-utils package which contains the programs pm-suspend, pm-hibernate, etc. To suspend to RAM, just do the following:

sudo pm-suspend

...and to hibernate...

sudo pm-hibernate

Pretty straight-forward! There is also a "hybrid", called pm-suspend-hybrid. What this does is that it does everything it needs to hibernate and then suspends the computer instead of shutting it down, as it normally would when hibernating! So if you do not run out of power during this suspended state, you can start the computer up again as if it was a normal supension—if you do run out of power, it would just act like a normal hibernation.

FireWire

FireWire is supported out of the box, however, for FireWire HD support, you might need to load the sbp2 module (that is, if you are using the common stack, since a new one is in the works and already present in the kernel). You have the common stack if you run stock Arch kernels.

Tactile strip

This laptop sports a fancy tactile strip, providing some extra buttons as well as volume control (toggling mute and changing volume). I have not tried yet to get hal working for my multimedia keys yet, the present solution works fine. Enter keytouch: The HP NC6320 settings (pre-supplied by keytouch) seem to work just fine for muting & adjusting the volume. The 'Help' key (left to the radio switch) fires up your DE's help center if everything goes well, the button to the right is recognised too (you have to configure it though ;-)).
As a fancy plus, you'll get a nice OSD when you mute/unmute or change volume.
